0.9a+4.96=3.6+1.4a what is the answer simplfy

1 answer:

4 0

Answer: a=2.72

Explanation:
Move all the terms containing a to the left side of the equation

-0.5a+4.96=3.6

Subtract 4.96 from right side

-0.5a=3.6-4.96

Would be

-0.5a=-1.36

Divide each term by -0.5 and simplify

a= 2.72

The hanger shown in the diagram is balanced. All cherries weigh the same, all mushrooms weigh the same, and all strawberries wei

aleksley [76]

Answer:

56 grams.

Step-by-step explanation:

In the sixth vertical string on the right, we have two cherries.

Since it is balanced, each of the other 3 strings(3rd, 4th and 5th) on the right will weigh two cherries.

Therefore:

Right Hand Side(3rd,4th,5th and 6th string) = 4 X 2 Cherries=8 Cherries

The fist string carries a weight of 2 Mushrooms

Therefore the second string will also weight Two Mushrooms.

Left Hand Side(1st and 2nd string)=2 X 2 Mushrooms =4 Mushrooms

Therefore:

Right Hand Side=Left Hand Side

8 Cherries=4 Mushrooms

One Cherry is 7 grams

Therefore:

4 Mushrooms =7 X 8 =56 Grams

The total weight of the left hand side is 56 grams. Therefore, the exotic fruit weighs 56 grams.

Well I'm having troubles with something I have no idea what it is or how to do it. The problem is x^2 -18x+8=0. I only know how

Lubov Fominskaja [6]

Answer:

$x = \frac{-(-18) -\sqrt{(-18)^2 -4*1*8}}{2} = \frac{18 -2 \sqrt{73}}{2}= 9 -\sqrt{73}$

$x = \frac{-(-18) +\sqrt{(-18)^2 -4*1*8}}{2} = \frac{18 +2 \sqrt{73}}{2}= 9 +\sqrt{73}$

Step-by-step explanation:

We have the following equation:

$x^2 -18 x +8 =0$

We can use the quadratic formula given by:

$x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}$

Where:

$a = 1 , b=-18, c =8$

And replacing we got:

$x = \frac{-(-18) -\sqrt{(-18)^2 -4*1*8}}{2} = \frac{18 -2 \sqrt{73}}{2}= 9 -\sqrt{73}$

$x = \frac{-(-18) +\sqrt{(-18)^2 -4*1*8}}{2} = \frac{18 +2 \sqrt{73}}{2}= 9 +\sqrt{73}$
